Ballistic test and numerical simulation on penetration of a boron-carbide-ceramic composite target by a bullet

  • 摘要: 碳化硼陶瓷具有高硬度、低密度的特性,在装甲防护领域有广泛的应用前景,碳化硼陶瓷及其复合靶的冲击破坏特性是装甲防护领域近期的焦点问题之一。本文中基于剩余穿深方法,开展了碳化硼及复合靶抗12.7 mm穿甲燃烧弹侵彻的试验研究。建立了碳化硼陶瓷复合靶抗弹数值模拟模型,根据试验研究结果验证数值模拟方法的可靠性。在此基础上,开展了12.7 mm穿甲燃烧弹侵彻碳化硼陶瓷复合靶的数值模拟研究,重点研究了靶板配置、背板厚度及种类对复合靶抗弹性能的影响。结果表明:靶板面密度相同的情况下,随着陶瓷厚度的增大,陶瓷复合靶的抗弹性能提高;陶瓷厚度相同时,陶瓷复合靶抗弹性能提升的效率随其面密度的增大而下降。陶瓷/PE (polyethylene)结构适合抵抗低速弹体的侵彻破坏,陶瓷/铝结构适合抵抗高速弹体的侵彻破坏。
